This article from News and Views discusses the observation and analysis of submarine volcanic eruptions. Volcanism underwater is unalike volcanism on land due to the differing qualities of water and air. Air is not as dense as water; the properties of air allow for larger eruptions than those that occur underwater (Mitchell 444). Pressure on the ocean floor does not allow water or gasses to escape from lava. This causes the eruption to have less of an impact underwater than it would if it were on
